Abstract Soil carbon (C) is a critical component of Earth system models (ESMs), and its diverse representations are major source the large spread across in terrestrial C sink from third to fifth assessment reports Intergovernmental Panel on Climate Change (IPCC). Improving soil projections high priority for modeling future IPCC other assessments. To achieve this goal, we suggest that (1) model structures should reflect real‐world processes, (2) parameters be calibrated match outputs with...
Significance One of the greatest challenges in projecting future shifts global climate is understanding how soil respiration rates will change with warming. Multiple experimental warming studies have explored this response, but no consensus has been reached. Based on a synthesis 27 spanning nine biomes, we find that although increases rates, there limited evidence for shifting response We also note universal decline temperature sensitivity at temperatures >25 °C. Together, our data...
Climatic changes are altering Earth's hydrological cycle, resulting in altered precipitation amounts, increased interannual variability of precipitation, and more frequent extreme events. These trends will likely continue into the future, having substantial impacts on net primary productivity (NPP) associated ecosystem services such as food production carbon sequestration. Frequently, experimental manipulations have linked regimes to NPP. Yet, findings been diverse uncertainty still...
Abstract Phosphorus limitation on terrestrial plant growth is being incorporated into Earth system models. The global pattern of phosphorus limitation, however, remains unstudied. Here, we examined the global‐scale latitudinal by analysing a total 1068 observations aboveground production response to additions at 351 forest, grassland or tundra sites that are distributed globally. observed phosphorus‐addition effect varied greatly (either positive negative), depending significantly upon...
The denitrification process profoundly affects soil nitrogen (N) availability and generates its byproduct, nitrous oxide, as a potent greenhouse gas. There are large uncertainties in predicting global because controlling factors remain elusive. In this study, we compiled 4301 observations of rates across variety terrestrial ecosystems from 214 papers published the literature. averaged rate was 3516.3 ± 91.1 µg N kg-1 day-1 . highest 4242.3 152.3 under humid subtropical climates, lowest 965.8...
Abstract Soil microbes play critical roles in regulating terrestrial carbon (C) cycle and its feedback to climate change. However, it is still unclear how the soil microbial community abundance respond future change scenarios. In this meta-analysis, we synthesized responses of experimental warming from 64 published field studies. Our results showed that significantly increased by 7.6% on average. When grouped vegetation or types, tundras histosols had strongest with microbial, fungal...
Abstract Soil microbial respiration is an important source of uncertainty in projecting future climate and carbon (C) cycle feedbacks. However, its feedbacks to warming underlying mechanisms are still poorly understood. Here we show that the temperature sensitivity soil ( Q 10 ) a temperate grassland ecosystem persistently decreases by 12.0 ± 3.7% across 7 years warming. Also, shifts communities play critical roles regulating thermal adaptation respiration. Incorporating functional gene...
Abstract. Terrestrial ecosystems have absorbed roughly 30 % of anthropogenic CO2 emissions over the past decades, but it is unclear whether this carbon (C) sink will endure into future. Despite extensive modeling and experimental observational studies, what fundamentally determines transient dynamics terrestrial C storage under global change still not very clear. Here we develop a new framework for understanding through mathematical analysis numerical experiments. Our indicates that ultimate...
Past global change studies have identified changes in species diversity as a major mechanism regulating temporal stability of production, measured the ratio mean to standard deviation community biomass. However, dominant plant functional group can also strongly determine stability. Here, grassland ecosystem subject 15 years experimental warming and hay harvest, we reveal that increases while harvest decreases This corresponds with biomass C4 being higher under lower harvest. As secondary...
Abstract Nitrogen immobilization usually leads to nitrogen retention in soil and, thus, influences supply for plant growth. Understanding is important predicting cycling under anthropogenic activities and climate changes. However, the global patterns drivers of remain unclear. We synthesized 1350 observations gross rate (NIR) from 97 articles identify NIR. The mean NIR was 8.77 ± 1.01 mg N kg −1 day . It 5.55 0.41 croplands, 15.74 3.02 wetlands, 15.26 2.98 forests. increased with annual...
Abstract The spatial and temporal variations in terrestrial carbon storage play a pivotal role regulating future climate change. However, Earth system models (ESMs), which have coupled the biosphere atmosphere, show great uncertainty simulating global land storage. Here, based on multiple datasets traceability analysis, we diagnosed source of 22 ESMs that participated phases 5 6 Coupled Model Intercomparison Project (CMIP5 CMIP6). modeled has converged among from CMIP5 (1936.9 ± 739.3 PgC)...
Abstract Land use change (LUC) alters the global carbon (C) stock, but our estimation of alteration remains uncertain and is a major impediment to predicting C cycle. The uncertainty partly due limited number geographical bias observations, exploration its predictors. Here we generated comprehensive database 5,980 observations from 790 articles. sites evaluated at least seven times larger than in previous meta‐analyses. Our constrained estimates different LUC's effects on soil organic (SOC)...
Plant-microbe interactions are considered to be important processes determining the efficiency of phytoremediation petroleum pollution, however relatively little is known about how these influenced by pollution. In this experimental study using a microcosm approach, we examined plant ecophysiological traits, soil nutrients and microbial activities were pollution in Phragmites australis, phytoremediating species. Generally, reduced performance, especially at early stages growth. Petroleum had...
Summary Long‐term, slow ecological processes such as changes in plant community structure and composition strongly regulate ecosystem responses to climate change. Shifts are expected chronically altered environments under warming. However, experimental evidence for long‐term shifts the associated mechanisms is still scarce temperate grasslands. Here, we explore of a prairie 14‐year (2000–2013) manipulations warming clipping O klahoma, USA . Infrared heaters were used elevate soil temperature...
